hi! Yes, I've followed the thread about calling dtml methods, but I couldn't get very much out of it concerning my following problem (maybe I should read it again?). I have a similar problem, but my dtml is created dynamically: folder "sayhello/": dtml method "template": ----------------------------------- <dtml-var standard_html> <h3>$GREETING$</h3> $INTRODUCTION$ <dtml-var standard_html_footer> python script "personalize" (only parameter: "document") ----------------------------------- from string import replace personalized = getattr(context, document).document_src() personalized = replace(personalized, '$GREETING$', 'this is the greeting') personalized = replace(personalized, '$INTRODUCTION$', 'this is the introduction') return personalized (of course the strings will be replaced by calls like "getGreeting", "getIntroduction" :-) just testing right now) dtml method "index_html" ----------------------------------- <dtml-var "personalize('template')"> Yes, I could do the dollar sign stuff with dtml variables, but I don't want the editor to be able to use dtml in general, just a couple of "variables" provided by me. So I invented some names and give him the opportunity to include some simple texts/numbers that might be useful inside his text. (-> he can edit "template") Of course this returns crap: The python script takes the raw, unrendered dtml source, replaces a few strings, and returns that unrendered source. "Dynamically created DTML" means I want to render the document_src *after* replacing. I understand that I could create an external method contatining something like from OFS.DocumentTemplate.DT_HTML import HTML def renderDTML(DTML, namespace=None, **kw): ob = HTML(DTML) return ob(namespace, kw=kw) (which I would do if totally necessary), but since I'm using an INSTANCE_HOME, I don't know how do the import correctly, I always get an error when trying to add an external method containing the above, that sits in my "Extensions" directory.
